Frequently asked questions about Macupatide

What is Macupatide used for?

Macupatide is an investigational drug being studied for weight management in adults with obesity or overweight. It is also being tested in people with obesity or overweight who have type 2 diabetes. It has not been approved for any use and remains in clinical development.

Who is developing Macupatide?

Macupatide is being developed by Eli Lilly and Company, which trades on the New York Stock Exchange under the ticker LLY. Lilly is running the clinical program, including studies of Macupatide alone and in combination with eloralintide.

What phase is Macupatide in?

Macupatide is in Phase 2 clinical development for obesity and overweight. One Phase 2 trial is currently recruiting, another Phase 2 trial is active but not recruiting, and a Phase 1 study in Japan has not yet started recruiting. It is not FDA approved.

What clinical trials is Macupatide in?

Macupatide is being studied in NCT07589608, a recruiting Phase 2 trial of Macupatide and eloralintide alone or in combination in adults with obesity or overweight, and NCT07215559, an active Phase 2 trial in adults with obesity or overweight and type 2 diabetes. A Phase 1 trial, NCT07765511, is planned in Japan.

Is Macupatide the same as LY3532226?

Yes, Macupatide is also known as LY3532226. Trial records list the drug under both names, so searches for either term refer to the same Eli Lilly investigational compound being studied for obesity and overweight.

How is Macupatide being tested in clinical trials?

The Macupatide trials are randomized, double-blind, and placebo-controlled, with about 400 participants enrolled in the Phase 2 study of Macupatide and eloralintide. Participants are adults aged 18 and older with obesity or overweight, and the studies are running in the United States and several other countries.
